Technology Connections talks about a red fridge from Walmart for an hour (youtu.be)

In a video by @[email protected], Alec goes into a deep dive into the simplicity of his particular model, its shortcomings and variety of data logging tests in an attempt to fix them.

TL,DW: Very simple, cheap and ingenious design, with one compressor loop between the fridge and freezer in series. However, its temperature sensor is wonky and so the fridge is more affected by how long the compressor operates than the actual temperature itself. There is a signficant temperature differential between the top and bottom, fans on the exterior or interior could help but with the faulty sensor only made matters worse. With the controller replaced with a proper temp control unit the fridge functioned much better.

8C is about 46F.

Right from the USDA government agency.

Bacteria grows more rapidly in food starting at about 40F.

I think I'll trust the food safety agency over some random pretentious guy on Lemmy thanks very much.

Sorry for only telling how it is in europe. Here in Germany the desired fridge temperature according to state guidelines should be 7-8°C and that's what I'm commenting. Just pointing out that the differences are stunning and funny.

Typical European attitude I see

I'm sorry but what is the typical attitude here? Finding it interesting how things and standards differ between regions? Do you feel judged by me just stating the fact that in Europe we use a different fridge design than Americans do?

Interesting how different international standards are. 3-4°C seems like a big difference between the agencies!

Do you have a source for the 8°C claim?

[–] [email protected] 1 points 1 year ago

I of course only know how things are done here in Germany with my whole life living here.

But someone else found a stackexchange thread about specifically this topic: https://quex.cc/comment/72381

It's a bit more nuanced than that:

They said up to 8°C is fine for most of the stuff, 4°C for meat and 2°C for minced meat
